Wearable customized ear canal apparatus
The present invention is directed to a wearable system wherein elements of the system, including various sensors adapted to detect biometric and other data and/or to deliver drugs, are positioned proximal to, on the ear or in the ear canal of a person. In embodiments of the invention, elements of the system are positioned on the ear or in the ear canal for extended periods of time. For example, an element of the system may be positioned on the tympanic membrane of a user and left there overnight, for multiple days, months, or years. Because of the position and longevity of the system elements in the ear canal, the present invention has many advantages over prior wearable biometric and drug delivery devices.

a medial ear canal assembly including a transducer configured to be positioned on a tympanic membrane of a user;
a lateral ear canal assembly including a signal source configured to be positioned in an ear canal of a user; and
sensors connected to the medial ear canal assembly, the sensors being connected to a transmitter, wherein the sensors include sensors adapted to detect biometric data.
2. A system according to claim 1 , wherein the sensors include sensors adapted to detect one or more physical characteristics of the user.
3. A system according to claim 1 , wherein at least one of the sensors comprises a microphone.
4. A system according to claim 3 , wherein the microphone comprises a micro-actuator.
5. A system according to claim 4 , wherein sound received by the micro-actuator is configured to be converted to a back EMF signal.
6. A system according to claim 5 , wherein the system includes a data processor which is configured to convert the back EMF signal to a signal representative of the sound received by the micro-actuator.
7. A system according to claim 6 , wherein the system is configured to transmit the signal representative of the sound received by the micro-actuator to a receiver external to the system.
8. A system according to claim 7 , wherein the receiver comprises a smart phone, a wireless network, or a peripheral device.
